Concerned for my leopard gecko :(?

I would switch to paper towels right away. The "digestible" sand isn't digestible at all, and is actually worse because it encourages the lizards to eat it. Paper towels are cheap, her teeth won't get caught, they're very clean (no dust, or mud when it gets wet) and there is no risk of impaction either way... it is not the prettiest substrate, but it really doesn't look bad, and in my opinion is the best to work with. Hope I helped.
